Keep the query string across the about redirects

The hop to the trailing-slash form of the about page, and the hop back
to the summary of a repository without a readme, were built from the
path alone, so a request for the about page of another branch landed
on the default one. The query goes into the Location line as the
client sent it, with any byte a header cannot carry percent-encoded.
